- Barotrauma's projects are in the Barotrauma directory - All libraries are in the Libraries directory - MonoGame is now managed by NuGet, rather than referenced from the installed files (TODO: consider using PCL for easier cross-platform development?) - NuGet libraries are not included in the repo, as getting the latest versions automatically should be preferred - Removed Content/effects.mgfx as it didn't seem to be used anywhere - Removed some references to Subsurface directory - Renamed Launcher2 to Launcher
